Objectives Recurrent varicose veins following surgery is a common, complex and costly problem in vascular surgery. Treatment for RVV is technically more difficult to perform and patient satisfaction is poorer than after primary interventions. Nevertheless, traditional vein surgery has largely been replaced by percutaneous office-based procedures, and the patients with recurrent varicose veins have not benefited from the same advantages. In this paper, we propose an endovascular laser treatment that allows reducing the invasiveness and complications in case of SFJ and SPJ reflux after ligation and stripping of the great and small saphenous vein...

Purpose: Teaching ultrasound procedures to undergraduates has recently been proposed to improve the quality of medical education. We address the impact of applying standardized dermatologic ultrasound teaching to our undergraduates. Materials and Methods: Medical students were offered an additional theoretical and practical seminar involving hands-on ultrasound dermatologic ultrasound during their mandatory dermatology practical training. The students' theoretical knowledge and dermatologic ultrasoud skills were tested with a multiple choice questionnaire extracted from Level 1 Spanish Society of Ultrasound Dermatologic Ultrasound accreditation exam before and after the course...

BACKGROUND: Blocking conduction in the saphenous nerve is important in providing surgical anesthesia of the lower leg. The aim of this retrospective study was to determine the efficacy of ultrasound-guided paravenous approach for saphenous nerve block. METHODS: Twenty-eight patients underwent ankle surgery after saphenous nerve block using ultrasoud-guided paravenous approach below the knee combined with sciatic nerve block under general anesthesia. Sensory blockade was evaluated at the upper part of the leg as compared with the contralateral leg...

BACKGROUND: Invasive prenatal diagnosis (IPD) allows identification of fetal diseases, mainly aneuploidy. With the addition of first-trimester prenatal screening and structural ultrasound, IPD indications have changed. OBJECTIVE: To describe the current indications for IPD in pregnant patients at INPer. METHODS: Descriptive and retrospective study. We reviewed medical records of patients in which IPD was performed during a period of 2.5 years...

There are increasing numbers of elective surgeries not only for abdominal aortic aneurysm repair but also for emergencies because of ruptured aneurysms (rAAA). Mortality rates of rAAA up to 40-50% have remained unchanged for years. Because of the elevated incidence of complications in rAAA, the overall mortality is at least 80% and shows a dismal prognosis for this group of patients. With ultrasonography, a cost-efficient, technically simple and safe method with high sensitivity is available for detecting abdominal aortic aneurysms...

BACKGROUND: Although rotational atherectomy (RA) have been proven to be effective in calcified and non-dilatable lesions in Kawasaki disease, long-term efficacy and safety have not been established. METHOD: To evaluate long-term outcome, follow-up (FU) information was analyzed in 26 patients with Kawasaki disease, or 30 calcified and non-dilatable lesions with adjunctive balloon(BA) dilatation after RA from May 1993 to December 2002. Patient and lesion characteristics were: age 15 +/- 5 (8-28) years(yrs), and male-77%, previous myocardial infarction(MI)-4%, multi-vessel disease-35%, coronary aneurysm-87%...

Cerebrovascular Moyamoya disease (MMD) is a clinical entity characterized by stenotic or occlusive lesions around the terminal portions of the internal carotid arteries (ICA) and the formation of abnormal vascular networks at the base or convexity. This condition is sporadic, and there are no pathological explanations for this cause. A case with unilateral juvenile MMD is reported. A 13-year-old girl with sudden episode of left limbs weakness, accompanied by transient dysphasia and seizures attack, was admitted to our hospital for further investigation...

OBJECTIVE: Thalamic brain haemorrhage is a common disabling and potentially fatal condition. However, management is mainly supportive, very rarely do neurosurgeons resort to evacuation of the haematoma. We hypothesised that cerebral haemodynamic abnormalities in the forms of lost pressure autoregulatory response (PAR) and/or impaired cerebral vasoreactivity (CVR) to carbon dioxide may indicate the haematoma should be aspirated to prevent further brain damage. MATERIAL AND METHODS: Patients with thalamic haemorrhage were selected on clinical ground for intracranial pressure (ICP) monitoring and intensive care management...

An algorithm for the estimation of one-dimensional in-vivo ultrasound pulses is derived. The routine estimates a set of ARMA parameters describing the pulse and uses data from a number of adjacent rf lines. Using multiple lines results in a decrease in variance on the estimated parameters and significantly reduces the risk of terminating the algorithm at a local minimum. Examples from use on synthetic data confirms the reduction in variance and increased chance of successful minimization termination. Simulations are also reported indicating the relation between the one-dimensional pulse and the three-dimensional, attenuated ultrasoud field for a concave transducer...
